Realistically it just means they doing the same virtue signaling in the comics as they're doing on film.
None of these characters were gay when they were first introduced. I don't mind gay characters but..
I find it suspicious that they are exclusively using black people to represent queerdom.
in fact, i bet the first gay white character we see in the MCU will still be in a relationship with a black person.
Hollywood diversity strategy 101.
If you want to show interracial relationships , show a white guy smashing a woman of another race to make it more palatable to white audiences. Self hating people with aspirations of being future whites actually prefer it this way.
If you want to represent multiple races in your film, have them be women, so you can also check off the gender diversity box at the same time.
If you want to represent other sexualities, have the gay character be non white so can check off multiple racial diversity boxes at the same time.
if you are forced to center a film around a strong hetero black male lead, include at least one white male protagonist for the white audience to identify with.
